High performance adjustable thermostatic diverting valves. Its material is yellow brass.The pre-assembled kit, by means of a stainless steel flexible pipe, makes a counter-current circulation that warms the water along the recycling way.

Technical specifications:

Maximum static pressure 10bar(PN10), dinamic 5bar

Maximum ratio between the pressures: 2:1

Maximum inlet temperature: 95°C

Setting temperature range: 35-60°C

Setting stability: ± 2°C

Maximum Kvs: 4,0 (82 l/min, 1,5 bar)

The scald protection function stops automatically the hot water running if the cold water of necessarymixing is not enough.

The tests are finished in the laboratory with 1 bar differential pressure just the valve itself:DN20 Kvs 4,0, the regulator in third position: Thot=65°C, Tcold=15°C, Tmix=51°C, (65l/min)

2-way unmixed pump unit 3/4"

DN20 pump units can be connected to heating systems with powers up to 35kW, with very low energy consumption assured by high efficiency synchronous circulating pumps. The connections to the distribution headers are made in ¾” thread (male on the distributor side and female on the loop side).

Compact and up-to-date, the new series offers functions similar to those of the bigger sizes DN25 and DN32. Especially suitable to manage medium-low powers in small rooms, thanks to its centre distance of only 90 mm.

Euroster 11Z controller

Electronic, programmable thermostat designed for control of both: CH and DHW pumps independently.

Controller function:

prevents boiler sweat

keep constant temperature in the tank

switches on the hot water priority function

blocking function against tank cool down

anti-stop function to protect pumps against stoppage

frost protection

pump operation test

temperature reading correction

E11Z controller is equipped with two temperature sensors and AntiStop function with a possibility to turn a DHW priority on. The controller prevents boiler condensation, maintains a constant temperature of water in the tank.Euroster 11Z is a modern controller that independently controls operation of two pumps:central heating circulating pump and hot water tank loading pump with the possibility of prioritizing hot water pump.The controller switches off central heating pump if temperature of the heating boiler falls belowa predefined value. If tank temperature falls down, tank loading pump will be switched off. Moreover, the controller protects the tank against cooling down in case of low temperature or fire extinction. Hot water priority function allows for the fastest possible way of heating the tank.

Fixing controller:

Fix the controller on a wall and other support with the use of two screws (rawbolts with screws come with the regulator),

Attach the cables lead out of the controller to the wall with the use of grips.

Electronic DHW tank with exchanger

These water heaters represent a compact assortment of indirect enamelled water heaters with volumes between 80–1000 litres.

By choosing the appropriate type of water heater and its volume you may prepare hot utility water using the external power sources, such as gas boilers, solid fuel boilers, alternative power sources, heat exchange stations, district heating and their combinations.

Some types may be ordered with the auxilliary electric heating or added with heating units from the accessories section.
